Primary central nervous system lymphomas

In this review, we discuss primary central nervous system lymphomas: a rare type of tumours confined to the central nervous system. The disease is associated with a poor prognosis, which, however, generally has seen steady improvement over the last four decades, particularly in the younger population. Modern surgical techniques are reserved for diagnosis and has no place in the treatment, which mainly relies on high-dose polychemotherapy treatment regimes with methotrexate as the backbone.
